Why Are Indian Children Shorter Than African Children?∗
Height-for-age among children is lower in India than in Sub-Saharan Africa. This presents a puzzle since India is richer than the average African country and fares better on most other development indicators including infant mortality. Using data from African and Indian Demographic and Health Surveys, we document three facts. First, among firstborns, Indians are actually taller than Africans; t...
متن کاملSpastic muscle cells are shorter and stiffer than normal cells.
The mechanical properties of isolated single muscle fiber segments were measured in muscle cells obtained from patients undergoing surgery for correction of flexion contractures secondary to static perinatal encephalopathy (cerebral palsy). "Normal" muscle cells from patients with intact neuromuscular function were also mechanically tested. Fiber segments taken from subjects with spasticity dev...
متن کاملShorter mothers have shorter pregnancies
We assessed whether maternal height was associated with gestational age in a cohort of 294 children born at term. Increasing maternal height was associated with longer pregnancy duration (p = 0.002). Stratified analyses showed that the main effect on pregnancy length appears to occur among shorter mothers (<165 cm tall), whose pregnancies were ∼0.6 and ∼0.7 weeks shorter than pregnancies of mot...

Introduction We have all heard the old joke of school being all about the three “R’s”, Reading ‘Ritin and ‘Rithmatik, but because of increasing class sizes and reported lack of instruction time, writing has been passed over for the more “important” subjects. The advent of computers and the increasing ease of word processing have given teachers the ultimate excuse, but most beginning composition...
متن کاملDetection of shorter-than-skin-depth acoustic pulses in a metal film via transient reflectivity
Short acoustic pulses are generated in SrRuO3 transducers and detected at the surface of gold films by transient reflectivity. Contrary to expectations, acoustic pulses that are shorter than the optical skin depth of gold are resolved. A comparison of gold detection films that were grown under different deposition conditions demonstrates that the microstructure of a detection film can impact th...
